It's being leaked out gradually - probably to soften for news that GB may not be actually the full tilt:

"Brown has recently been given a "long list of forbidden foods". The civil servant, who works regularly with the PM, told Ward that Brown had been banned from eating and drinking several specific things "because of the drugs he's on".

Top of the list of foods that Brown can no longer touch, the source told Ward, were cheese, Chianti and over-ripe avocados - which immediately rang alarm bells for Ward. "Every doctor in Britain would recognise these contra-indications instantly: for they are the great verbotens for people taking MAOI drugs."

MAOIs - which stands for Mono Amine Oxidase Inhibitors - are generally a last line of treatment for major depression, when other anti-depressant drugs have failed. They can also be very effective in treating OCD. But they are potentially extremely dangerous. If the patient eats or drinks the wrong thing, they can result in death – hence the PM's "long list of forbidden foods".
